After the installation, users can decide which messages they want to receive

alarms (emergencies), safety (e.g. meteorological warnings), breakdowns (e.g. water and sewage), housing estate (neighbourhood messages directed from individual housing estate councils), air (smog reports, exceeded dust particle limits, free communication), transport (road works, communication difficulties)..
